Perry's had no shortage of projects since wrapping up the album's California Dreams tour: among others, she produced and starred in a 3D concert film (which also chronicled her split with ex-husband Russell Brand), Part of Me; reprised her role as Smurfette in the animated The Smurfs 2, due July 31; and announced her latest fragrance, Killer Queen.

The multi-platinum Teenage Dream made Billboard history with five No. 1 singles, a single-album record for a female artist. In 2012, she was named Billboard's Woman of the Year.
